Zinc rich primer is a cold galvanising paint for iron and steel; use as a self-finish coating or a durable, weld through rust inhibiting primer beneath many of our top coats. Suitable for all ferrous metals, such as carbon steel, stainless steel, mild steel, cast iron and wrought iron.
Recommended for the protection of: structural steel work; agricultural and construction plant and machinery. Also great for gates, railings, iron, pipework. Helps prevent rust and corrosion where existing galvanised surface has been damaged by cutting or after welding as a weld through primer.
Highlights
- Carbogalv cold galvanising zinc primer paint provides cathodic protection to ferrous metal surfaces
- Protect structural steel work, agricultural and construction plant and machinery, gates, railings, iron pipework and guttering
- Prevent rust creep caused by cutting or in-situ welding work
- Clean and thin with Palatine Paints Multi Purpose Thinners
Allows conductivity as a dried film. Touch dry in 3 hours. Suitable for brush or spray application. For small areas or damage repairs see Bright Zinc Cold Galvanising Spray

Our zinc rich primer is a ‘galvafroid’ equivalent. Also known as weld through primer with it’s unique formulation and high quantity of ultra fine premium quality zinc dust. The zinc acts in a sacrificial manner when in direct contact with the iron or steel substrate and providing galvanising properties.
Please note: This primer should not be used on surfaces that have been treated with phosphoric acid.
Preparation:
Proper surface preparation is essential for the success of any protective coating system. Before you begin ensure the area is free from any dust, oil, grease, old coatings and surface contaminants.
Rub down previously gloss painted surfaces with fine waterproof abrasive paper and rinse thoroughly.
Application:
Best results are obtained in warm (minimum 10°C), dry conditions.
Mix thoroughly for approximately 2 minutes using a drill stirrer. A wooden batten at least 25mm wide is also ideal.
Apply an even coat using a brush, short to medium pile roller on smooth surfaces.
Please note: The colours on the product listings are only given as a guide. This is due to the fact that every computer monitor has a different capability to display colours. In addition, everyone sees these colours differently. Sample pots are available to order upon request. Always carry out a test patch (approximately 100x100mm) before full application to ensure compatibility with previous coatings and the substrate, and to ensure the colour achieved meets your requirements. Failure to do so will result in a product refund claim not being accepted.

This seems to be an excellent quality zinc-rich primer – very heavy weight gives a clue – and easy to apply.
